There's no way to do that; many have asked, none have succeeded.  Maybe that'll be a feature of the soon-to-be-arriving-soon new forum software.  Plus OP doesn't really want his account deleted, because he seems like the type who'll just keep coming back whenever it suits his purposes, and when he inevitably runs up against the brick wall of moderation he'll continue to bitch about it.  Some people outgrow bitcointalk within a year or two, and some people linger far past the point when they should have left.

Wow, could you cram any more platitudes into such a short post?  Also, you don't have to believe in time.  It exists, and even the worst tin-foil conspiracy theory nutjobs won't dispute that.  Jesus, the shitposting around here is getting stinky.  Somebody please open a window.
